Definitions

  • the present invention firstly relates to a method for presetting a central ventilation system for ventilating two or more spaces of a building, comprising one or several ventilators and two or more supply and/or discharge ducts for supplying or discharging air to or from these spaces, in which two or more supply and/or discharge ducts comprise a valve and/or flow controller for each supply or discharge duct, in which the maximum ventilation capacity for each supply or discharge duct is set with a valve and/or flow controller by setting the maximum passage opening of the valve and/or the flow controller.
  • the present invention relates to a presetting system for presetting a central ventilation system, in which this ventilation system comprises one or several ventilators and two or more supply and/or discharge ducts for supplying or discharging air, in which two or more supply and/or discharge ducts comprise one valve and/or flow controller for each supply or discharge duct, in which case the maximum ventilation capacity for each supply or discharge duct can be set by means of a valve or flow controller by setting the maximum passage opening of the valve and/or flow controller.
  • the present invention relates to a central ventilation system comprising a presetting system of this type.
  • a first system is a central mechanical extraction system (also referred to as a C system), in which the air is actively discharged from the dwelling. However, the supply of air takes place in a passive manner in this case.
  • the windows are usually provided with ventilation grilles or cantilever windows which are in communication with the outside air.
  • a special ventilation motor sucks air out of the humid spaces, such as the kitchen, the bathroom and the toilet, via air ducts and ventilation grilles.
  • a second system is a central mechanical ventilation system (also referred to as a D system), in which air is mechanically supplied from and discharged to the outside. In most cases, these are high efficiency ventilation systems.
  • a heat-recovery unit in such a central ventilation system uses heat from the discharged air in order to partly heat the air supplied from the outside before this is passed into the spaces.
  • flow controllers are provided in each supply and/or discharge duct of such central ventilation systems in order to be able to adjust the air flow rate based on the requirement or demand.
  • This air flow rate may, for example, be adjusted based on the presence or absence of people, or based on air parameters, such as the CO 2 content of the air, the relative humidity, the temperature of the air, etc.
  • the maximum capacity (in m 3 /h or l/s or h -1 ) of air which is supplied to the spaces to be ventilated and/or the maximum capacity of air which is discharged is determined by law, based on the type of space, the volume or the floor surface of the respective space.
  • this maximum ventilation capacity can be set in various ways. However, in practice, there are still no effective presetting methods or presetting systems to enable this maximum ventilation capacity to be set accurately and preferably automatically.
  • an additional valve or grille is provided for each supply or discharge duct as an alternative for presetting the maximum ventilation capacity for each supply or discharge duct, and is placed in a fixed position when presetting the ventilation system, corresponding to this maximum ventilation capacity.
  • the positions to be preset are difficult to determine accurately. Initially, these valves are set in a theoretically determined position which corresponds to the maximum ventilation capacity to be set. In practice, however, due to pressure losses in the system, the set maximum ventilation capacity will in this way always deviate from the maximum ventilation capacity to be set. By means of measurements, repeated attempts will be made to adjust this set maximum ventilation capacity until it approaches the maximum ventilation capacity to be set more accurately.
  • the actual maximum ventilation capacity is measured for each supply or discharge duct and then adjusted slightly towards the maximum ventilation capacity to be set.
  • this also affects the maximum ventilation flow rate of the other valves in the other supply or discharge ducts, so that these may again deviate further from the maximum ventilation capacity to be set.
  • Accurately setting the valve or grille positions is therefore a time-consuming and labourious operation.
  • valves in which the valve position automatically adjusts according to the pressure difference across the valve. In this way, a more or less constant flow rate is achieved across a certain pressure range.
  • the drawback of such valves is their limited accuracy and the need for a certain pressure range across the valve.
  • Ventilation systems already exist in which this maximum ventilation capacity is set by setting the maximum valve position for each flow controller manually or by means of software.
  • the maximum open position for each flow controller can be determined based on the required ventilation capacity of the space to be ventilated and based on the pressure losses across the entire ventilation system.
  • the set maximum ventilation capacity at the set valve position will, in practice, always deviate from the maximum ventilation capacity which is actually to be set due to uncertainties regarding the calculation of the pressure loss.
  • repeated attempts will be made by means of measurements to adjust the maximum valve position until it more accurately corresponds to the maximum ventilation capacity to be set.
  • a central ventilation system according to the preamble of claim 1 is known from FR 2 914 401A1 .
  • the object of the present invention is to provide a method by means of which the valve position to be set which corresponds to the maximum ventilation capacity to be set can be determined more accurately, so that the maximum ventilation capacity can be set more accurately.
  • This object of the invention is achieved by a method for presetting a central ventilation system for ventilating two or more spaces of a building comprising one or several ventilators and two or more supply and/or discharge ducts for supplying or discharging air to or from these spaces, in which two or more supply and/or discharge ducts comprise a flow controller for each supply or discharge duct, in which this flow controller has an adjustable passage opening, in which the maximum ventilation capacity for each supply or discharge duct is set by setting the maximum passage opening of the flow controller, and in which this method comprises the following steps:
  • each flow controller at each measurement in step a is either in an open position, in which said flow controller allows a maximum flow to pass through, or in a closed position, in which said flow controller allows a minimum leakage flow to pass through.
  • the set of comparisons from which the required characteristics of the duct network of the ventilation system can be gathered in order to determine the passage openings to be set becomes significantly simpler.
  • step a furthermore at least one measurement is carried out, with at least two flow controllers being in their open position in which these allow a maximum flow to pass through.
  • step a at least one measurement is carried out with all flow controllers being in their open position, in which these allow a maximum flow to pass through.
  • the number of measurements which is carried out in step a is preferably at least one greater than the number of flow controllers.
  • the nominal flow for each flow controller is preferably determined and said nominal flow is imposed for each flow controller.
  • the pressure level of the one or several ventilators is preferably set to a certain pressure level.
  • step a the pressure level of the one or several ventilators is preferably set to a different pressure level and step a is repeated. If several measuring points with a higher or lower pressure level are taken into account, a more accurate result can be achieved. If the number of measurements in the successively performed steps a is chosen to be identical, a correct approximation of the maximum passage openings to be set will be achieved by averaging.
  • step b the flow coefficients C for each flow controller corresponding to the nominal flow are calculated on the basis of the measurements performed and the passage opening to be set for each flow controller is determined on the basis of these flow coefficients.
  • the required pressure level of the one or several ventilators is preferably determined on the basis of the measurements and the pressure level of the one or several ventilators is set to this required pressure level.
  • this pressure level is preferably chosen to be as low as possible is to ensure a minimal consumption of the ventilation system, which is however sufficiently high to be able to guarantee the maximum ventilation capacity. On the basis of the measurements, it will be more readily possible to choose this pressure level based on the consumption and the maximum ventilation capacity to be guaranteed than based on a characterization of the ventilation system which has been determined theoretically beforehand.
  • This required pressure level is preferably determined on the basis of the calculated flow coefficients.
  • the total supply or discharge flow with a specific embodiment of a method according to the present invention can be determined on the basis of the capacity and the pressure level of the one or several ventilators.
  • the object of the present invention is furthermore also achieved by providing a presetting system for presetting a central ventilation system for ventilating two or more spaces of a building, this ventilation system comprising one or several ventilators and two or more supply and/or discharge ducts for supplying or discharging air to or from these spaces, in which two or more supply and/or discharge ducts comprise a flow controller for each supply or discharge duct, in which this flow controller has an adjustable passage opening, in which case the maximum ventilation capacity for each supply or discharge duct can be set by setting the maximum passage opening of the flow controller, and in which said presetting system comprises a measuring device in order to measure the total supply or discharge flow of the ventilation system, comprises control means for setting the maximum passage opening for each flow controller and comprises a calculation unit for calculating the flow coefficients for each flow controller on the basis of measurements of the total supply or discharge flow at different positions of the flow controllers.

  • the object of the present invention is also achieved by providing a central ventilation system for ventilating two or more spaces of a building comprising one or several ventilators and one or several supply and/or discharge ducts for supplying or discharging air to or from these spaces, in which two or more supply or discharge ducts comprise a flow controller for each supply or discharge duct, in which this flow controller has an adjustable passage opening, in which the maximum ventilation capacity for each supply or discharge duct can be set by setting the maximum passage opening of the flow controller, in which this ventilation system comprises a presetting system according to the present invention as described above.

  • the ventilator housing (2) is provided with various second openings, each of which is designed to be brought into communication with a supply or discharge duct.
  • the central ventilation system is provided with a duct system which has not been illustrated in the figures, comprising various supply and/or discharge ducts which are, on one hand, in communication with said ventilation element (1) and, on the other hand, end in a respective space of the building, and which are designed to either supply outside air by means of the ventilation element (1) to a space or to discharge air from a space to the outside by means of the ventilation element (1).
  • One or several of these ducts may in this case be provided with
  • control of the flow controller(s) (4) is preferably based on one or several of these measured parameters.
  • the ventilation system may also be provided with an additional detection system for detecting the presence or absence of people in the respective spaces and the central electronic processing unit can also control the flow controller(s) (4) based on this presence or absence of people.
  • the flow controller(s) (4) preferably comprise a rotatably arranged, rigid valve leaf (7) by means of which the passage opening of the flow controller (4) can be set.
